Searched and recommended try disconnect neg battery cable. Reconnect to see if it is then working again.
Interestingly, this player lacks the usual pin-hole release for emergencies, but it does specifically warn against using discs that have stick-on labels. If that happens to be your case, here's a long shot: Maybe you can slide a credit card over the edge of the disc to at least make sure the label is flat where it has to be, then play for a moment to reposition the disc and use the card again. I would also keep on trying the normal eject procedure, but that's just me!
Here are a few things I found, hopefully, one will work. How to Remove Stuck CDs From Toyota CD Players | It Still Runs My prius cd-player is not ejecting cds nor is it playing them what can i do? | Yahoo Answers (This is not me)This happens to my 1999 Toyota Corolla's factory CD player from time to time. I just unplug the battery for about a minute, reconnected it, and then pressed the "eject" button (without turning the car on, or even inserting the key). Works every time! Good luck! This also works on a 2003 Avalon with a factory CD player and stuck CD. However, instead of disconnecting the battery, I just pulled out the "radio" fuse, which disconnects power from the unit with less hassle. Works beautifully! Turn the car off. While the car is off, hold the power and the eject button. Turn the car on.
Nothing helpful. "If an error message is displayed, refer to the following table and take the appropriate measures. If the problem is not rectified, take the vehicle to your Toyota dealer." The 'table' gives only 3 possible solutions: clean the disc, check compatibility, eject the disc.
Draw out the stuck CD using double-sided tape on a thin ruler. See post here: Best way remove stuck cd | PriusChat
